Modified files:
	src            : Polyhedron.cc Polyhedron.defs.hh 

Log message:
	Private methods strongly_minimize* now return a boolean which is false
	if the result is an empty polyhedron (this is consistent with the behavior
	of private method minimize()).
	Patched method widening_CC92_assign() to also work for NNC polyhedra.
